OSURC run June 25 - July 1 UT June 24-25 to June 30-July 1 civil Seventh night: UT 2014 July 1 Observers: Scott Adams, Don Terndrup (OSU) Support Astronomer: Olga Kuhn Telescope Operator: Steve Allanson Weather Summary: Smoky to the west, with structure in the sky at sunset from the western horizon nearly to the zenith. This is better than it was last night, which turned out to be a very good night. Calm winds. No ashfall. Scattered clouds intermittently throughout the 2nd half of the night. STARTING INSTRUMENT: LBC 01:40 UT: Doing calibrations LBC biases MODS prism lamps, z-band imaging flats 02:40 UT: Moving to position for sky flats 03:00: Flats begin 03:15 UT: Moving to OSU_Monitor NGC 4258 to assess conditions DIMM seeing variable around 1.0". 03:54: Start taking images. Not the most superb conditions, but within the seeing specifications. First red science image FW=1.03" 04:32 UT: Going to UVa_Pal5 fields. 04:45: Starting science exposures on Pal5mos01. Error message from filter posititioning, so re-starting script. 05:05 UT: Collimating then proceeding to Pal5mos02 05:18: Starting science. Seeing for this series is about 1.0" 05:54 UT: Starting science images for Pal5mos03 No science images on blue side. In the OB, the blue side was turned off. This seems to be an error in the OB file. This is also true for the OB file for the next pointing. Instead of editing the OBs, which may introduce additional problems, we will write the PI and proceed with a different program. This field will be marked as DONE on the scheduling tool: if it needs to be re-observed then the queue will need to be edited. Seeing in the red images was 0.8-0.9". 06:36 UT: Moving to OSU_Monitor M101 06:46: Starting science observations. Seeing about 1.0". 07:16 UT: Moving to OSU_Monitor NGC 6503 7:27: Starting science observations. Seeing about 1.0" 07:54 UT: Starting science observations on OSU_Monitor NGC 6946 08:16: Some thin clouds coming in from the NE 08:30 UT: SWITCHING TO MODS 08:54 UT: Have moved to target NGC 6946 for OSU_MAP program 09:05: Starting science OB 10:00: Clouds have cleared out 10:30: Clouds are back in the southeast 10:47 UT: Moving to a spectrophotometric standard -- Feige110 10:55: Starting observations of Feige110 - dual grating only Seeing ~1.5" 11:04: Clearing, but patchy clouds near the NE and SE horizons. Seeing ~1.8" 11:06 UT: Setting up to take twilight flats Reconfiguring back to LBC 11:25 UT: Actually starting to get useful twilights Taking twilights in V (lbcb) and r' (lbcr) Warning: there are scattered wispy clouds close to our current pointing
